The climber will fall about the same height h in both cases, but they will be subjected to a greater force at position 1, due to the greater fall factor.. In lead climbing using a dynamic rope, the fall factor (f) is the ratio of the height (h) a climber falls before the climber's rope begins to stretch and the rope length (L) available to absorb the energy of the fall,
Fall history is the strongest risk factor associated with subsequent falls. [28] Older people who have experienced at least one fall in the last 6 months, or who believe that they may fall in the coming months, should be evaluated with the aim of reducing their risk of recurrent falls. [29]
Every fall lessens the amount of impact a rope can later absorb, and hard falls can seriously compromise the strength of a rope, without showing obvious signs of wear. One definition of a 'hard fall' is a long fall (> 10–15 meters) with a fall factor greater than one. Manufacturers often recommended that ropes be retired if they sustain an ...
The safe fall distance is a function of the fall factor and the deployment of the "energy absorbers". As a rule of thumb for a factor 2 fall, a fall distance of approx 6 m (20 ft) will be required. This is equivalent to 2 stories of a building. If the fall clearance is less than this the worker may strike the ground before his fall is arrested.
Fall factor management. Multi-pitch climbers need to avoid the lead climber falling with no climbing protection in situ, so that they fall all the way down to the belayer and then the same distance again below the belayer. Such a fall has a fall-factor of 2 and will create significant strains on both the belay anchors and the belayer.
It is a common misunderstanding to think that the number of drop test falls (as conducted by the UIAA) is the number of real-life climbing falls a rope can sustain before it becomes unsafe. The drop test falls are of extreme severity and a real-life climbing fall will not often generate a comparable force.
The self-arrest is a climbing technique mostly used in mountaineering and alpine climbing where a climber who has fallen and is sliding uncontrollably down a snow or ice-covered slope 'arrests' their fall by themselves by using their ice axe and their crampons.
Rope solo climbing is climbing alone but with a rope to help arrest a fall, or for a self-rescue if required. [2] [3] Instead of having a belayer, the climber uses a self-locking device that will hold the rope in the case of a fall, and leads the route in a traditional climbing manner, placing climbing protection as they ascend. One end of the ...
